N2 - The Multiple Inputs Multiple Output (MIMO) antenna technique provides two transmission modes, MUX and DIV. The MUX mode increases data rate and, on the other hand, the DIV mode reliability or transmission range. In this paper, we propose an opportunistic transmission mechanism that adaptively changes the MIMO transmission mode to provide reliability for the seamless video streaming service. Also, our mechanism utilizes an extra detour path for resolving congestion. We aim to satisfy various QoS requirements of multi-priority video data packets by assigning different paths and MIMO modes to different priority packets. Thanks to the low overhead of a single detour path and the opportunistic MIMO transmission mode change, our proposed mechanism becomes a proper solution for the seamless video streaming service. By carrying out extensive simulations, we show that our mechanism improves the network throughput.
